OPERATING MECHANISM FOR CAN-SOLDERING MACHINES.

SPECIFICATION forming part of Letters Patent No. 416,539, dated December 3, 1889. Application filed June 29, 1889. Serial 1%. 315,966. (No model.)

To all whom it may concern:

Be it known that I, EDWIN E. ANGELL, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Soldering-Iron- Operating Mechanism for Gan-Soldering Machines, of which the following is a specification.

This invention relates to can-soldering machines in which a series of mandrels are moved progressively in a rectilinear direction while the can-bodies supported thereon are being acted on simultaneously bya series of soldering-irons; and it has for its object to provide means for raising and lowering the series of irons, so as to alternately hold them above and upon the can-bodiesheldon a number of the mandrels-for. moving the irons simultaneously back and forth laterally in a direction parallel with the line of progressive movement of the mandrels, the irons being moved with the mandrels when depressed and in the opposite direction when raised, and for simultaneously reciprocating the irons lengthwise to give them a rubbing action. These results I attain by the mechanism which I will now describe.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents a front elevation of a portion of an organized can-soldering machine to which my improved soldering-iron-operating mechanism is applicable. Fig. 2 represents an enlarged front View of the soldering-iron-operating mechanism, portions of the machine being omitted. Fig. 3 represents a section on line 00 a, Fig. 2, looking toward the left.

The same letters of reference indicate the same parts in all the figures.

I have shown my improved soldering-ironoperating mechanism as applied to the organized can-soldering machine shown and claimed in another application for Letters Patent of the United States filed by me concurrently L herewith, Serial No. 315,964; but I desire to state that the invention described and claimed in this application is not confined to the said machine, but may be used with any other suitably-organized can-soldering machine.

In the drawings, c 6 represent mandrel-carriers, which are connected inan endless chain or series by pivots z', and are provided with anti-friction rollers h, which run in grooves formed in fixed endless tracks a a. Said tracks are in the general shape of ellipses having flattened sides, and while the carriers are traveling along said sides they are moving in a rectilinear direction. The carriers are moved progressively on the tracks by any suitable means, preferably those shown in my other application above referred to. The carriers 6 support a series of mandrels 0, said mandrels being formed to support cylindrical can-bodies. The mandrels are directly supported by slides 19, which are supported by and adapted to move in the carriers. The mandrels are made in sections, which are supported by springs, so that the sections may be moved apart to expand the mandrel by tapering cores t, which are longitudinally movable within the mandrels. The expansion of the mandrels causes the clamping of the can-bodies thereon between the peripheries of the mandrels and clamps which are affixed to the slides p.

A full description of the mechanism above referred to and of its operation is given in my other application above referred to, to which reference may be had for a fuller understanding of the same.

While the mandrels are being moved along the straight portion of the course and are eX- panded to hold the can-bodies, the solderingirons B B are presented to said can-bodies. Said soldering-irons, of which there may be any desired number, are supported by a bar 0, having sockets or cavities C, in which said irons rest loosely. The acting faces of the irons are narrow ribs that project downward- I ly through slots in the bottoms of said s0ckets. The soldering-irons are free to rise and fall in the sockets O',so that they conform automatically to the thickness of the sheet metal of the can-bodies. The irons may be heated by any suitable means, as by gasburners arranged above them so as to direct their flames against the portions of the irons that are contained in the sockets.

Means are provided for raising and lowering the irons, and when they are lowered they are in position to bear upon the mandrelsupported calrbodies. The irons are reciprocated longitudinally, so that when they are incontact with the can-bodies they exert a rubbing action on the seams thereof. The irons are also movable laterally, and means are provided whereby they are moved in the same direction and at the same rate as the can-bodies when lowered and in the opposite direction when raised, so that the irons remain in contact with the can-bodies during the entire period of their depression, the contact of the irons with the can-bodies thus obtained being sufficient to effect the soldering operation.

The means here shown for effecting the above-described movements of the irons are as follows: The bar 0 is supported by ayoke or frame D, which is formed on a slide or base D, fitted to move in a horizontal guide E. Said guide has a vertical slide F at one end, which is fitted to move in a vertical guide G, affixed to the supporting-trame. The yoke D is provided at its end with cars which are perforated to receive transverse horizontal rods I I, afiixed to the ends of the bar 0, said yoke being adapted to slide in the ears of the yoke, so that the bar 0 is movable transversely. To the bar C is connected, by means of a rod J, affixed to cars on the bar 0, one end of a connecting-rod K, the other end of which is provided with a trundle-roll, which engages a cam L on the shaft it. Said cam is formed to impart the described reciprocating movement to the bar 0 and irons B through the connecting-rod K, thus giving the irons their rubbing motion. The yoke D is raised and lowered to elevate and depress the irons by means of a cam P on a shaft R, which is geared to the driving-shaft, and a connectingrod Q, having a trundle-roll at one end engaged with said cam and pivoted at the other end to an car 011 the guide E. The rotation of the shaft R causes the cam P through the rod Q, to alternately raise and lower the guide E, and with thelatter the yoke D, bar 0, and irons B. The irons are moved laterally to accompany a series of progressively-moving can -bodies, and then return to act on a new series by means of a cam B on the shaft R and a lever S, pivoted at T tothe supporting frame and having at one end a trundle-roll engaged with the cam R and at the other end a slot which receives a stud U 011 the yoke D. The rotation of the cam R oscillates the lever S and causes the latter to reciprocate the yoke D and bar 0, thus carrying the soldering-irons back and forth in the direction indicated by the arrows AA, the irons being raised when moving in the direction indicated by the arrow A and lowered upon the can -bodies when moving in the direction indicated by the arrow A.

My invention is not limited to thedetails of mechanism herein described, and the same may be varied in many particulars without departing from the spirit of the invention.

I claim- 1. The combination, with a series of progressively-moving mandrels, of a series of vertically and laterally movable solderingirons adapted to co-operate simultaneously with a number of the mandrels, a cam andintermediate devices alternately raising and de pressing said irons, and a second cam and intermediate devices whereby the irons are reciprocated laterally in directions parallel with the direction of movement of the mandrels, the second cam being timed to move the irons with the mandrels when the irons are depressed and in the opposite direction when the irons are raised, as set forth.

2. The combination, with a series of progressively-moving mandrels, of a series of vertically and laterally movable solderingirons, means for simultaneously raising and lowering said irons, means for reciprocating the irons laterally, and a cam and connecting-rod whereby the irons are simultaneously reciproeated transversely and thereby given a rubbing action, as set forth.

3. The combination, with the series of progressively-moving mandrels, of the socketed bar, the soldering-arms carried by said bar, said irons being arranged at right angles with the bar, the cam and connecting-rod whereby the bar is reciprocated to give the irons a longitudinal rubbing movement, and means for moving said irons vertically and laterally, as set forth.

4. The combination, with the series of progressively-moving mandrels, of the socketcd bar, the soldering-irons carried by said bar, the movable yoke supporting said bar, the cam and lever whereby the yoke is reciprocated to carry the irons laterally back and forth, and means for alternately raising and lowering the yoke-bar and irons, as set forth.

5. The combination, with the series of progressively-moving mandrels, of the socketed bar, the soldering-irons carried by said bar, the movable yoke supporting said bar, means for reciprocating said yoke to carry the irons laterally, the vertically-movable guide supporting the yoke, and the cam and connecting-rod whereby said guide with the yoke-bar and irons supported thereby are vertically reeiprocated, as set forth.

6. The combination, with a series of progressively-moving mandrels, of the socketed bar, the soldering-irons supported by said bar, the cam and connecting-rod whereby the bar and irons are reciprocated to give the latter a rubbing action, the yoke sup porting the bar, the cam and lever whereby the yoke with the bar and irons are reciprocated to carry the irons laterally back and forth, the vertically-movable guide supporting the yoke, and the cam and connectingrod whereby said guide is vertically reciprocated, as set forth.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 15th day of June, IO A. 1889.
